An entertaining IMAX feature, "Adrenaline Rush" takes a look at human reaction to a potentially risky situation, whether it be a child's first day at school or base jumping off a giant cliff. While all humans share the common reaction to danger of feeling that rush that focuses our senses, there are those out there who seek out that rush, trying to find bigger and better ways to experience that energy.

The picture opens discussing Leonardo da Vinci's idea to try to come up with the first human parachute, which he drew diagrams of, but never was able to test. The film also introduces us to a skydiving couple who have invented a "flight suit" that allows them to stay up longer, resulting in flight records. In the film, we see them (joined by a series of scientists) try to construct Da Vinci's parachute and successfully jump with it. Other scenes include a group of skydivers playing catch with a tennis ball in midair.

Interestingly, this is an IMAX feature that's got its weight shifted more towards showing remarkable sequences than education (although it varies, most IMAX films are around a 50/50 balance in terms of education/entertainment). The film does talk about the bodily reaction that people have in terms of facing risks like skydiving, but that section is fairly brief. "To The Limit" is an IMAX feature that offers a bit more balance with a similar subject - athletes and the reaction their bodies have to stress, etc.

While the film isn't too educational, it does have superb visuals, such as a series of skydiving scenes, as well as ones following base jumpers off cliffs. The final sequence, which follows a base jumper off a cliff - from their point of view - is an amazing moment (although admittedly, it was a bit more stunning on the large screen). Overall, I wish this documentary would have been a bit more substancial, but it is technically well-done and does offer some entertainment.
